An urn contains 3 white balls and 4 black balls. A ball was drawn and without knowing its color, was then put inside a second urn that contains 3 white balls and 3 black balls. What is the probability that a black ball can now be drawn from the second urn?

An urn contains 5 white and 10 black balls. A fair die is rolled and that number of balls is randomly chosen from the urn. What is the probability that all of the balls selected are white? What is the conditional probability that the die landed on 3 if all the balls selected are white?
